Binding comboBox cell on change of another comboBox cell in RadGridView

[Hareesh]

Hi,
We are using RadGridView in our project. Now we have a requirement like: One grid view, which is binded with data from a table. Grid is having two combobox columns. First combo is filled with values from one table, and other combo need to bind with data from different table based on the value selected in the first combo. I have searched in the examples & I did not find any sample code. This is the first time i am using telerik controls. Please help..

Hello Hareesh,

You may review this blog post. There is an implementation of a common scenario when entering data is a cascade of combo boxes. The list in the next combo is populated after selecting a value in the previous.

Does this blog answer your questions?

I tried this solution, but on the following line I am getting a NullReferenceException error. It says the location object is Null, even though the comboBox.DataContext is properly populated with data...

location.ContinentCode = (string) comboBox.SelectedValue;

Ignore my post above, I was setting it to the wrong object type...
